      REVOLUTIONIZING RESIDENTIAL ESS! The BigBattery 48V ETHOS systems are here, and this 5.12kWh battery module is the building block for these stackable, scalable power systems. Our ETHOS systems are designed for every grid-tied home, solar setup, off-grid homestead, and commercial office in America. Each battery module is equipped with Tier 1 LiFePO4 cells, the safest chemistry on the market today, and has a capacity of 100Ah, with each ETHOS System being expandable up to 80kWh per Control Box simply by adding additional battery modules.


      Each module is also equipped with an advanced Battery Management System (BMS) that continuously monitors and records cell voltage, along with real-time data on current, voltage, and temperature for the module. The BMS features a passive cell balancing function and an advanced battery control method, which collectively enhance battery pack performance. Furthermore, the battery includes a built-in fire-extinguishing module for unmatched peace of mind. These modules utilize standardized UL-certified ESS connectors, which safely and reliably secure power to and from the battery. Designed to endure the test of time, the ETHOS has a lifespan of over 10 years and is engineered to withstand more than 4000 – 8000 cycles at 80% Depth of Discharge (DOD) at a rate of 0.5C.


      Our ETHOS Systems were built to be versatile on or off-grid power solutions, with a stackable, modular design for easy expandability, and all hardware included to mount your ETHOS to your wall with an effortless installation. Plus, the ETHOS comes equipped with an IP65-rated casing, to ensure long-lasting reliability and protection.


      Whether you’re looking to ensure emergency backup power is always available, or you’re looking to outfit your family home, cabin, or homestead with a powerful solar system, the ETHOS ensures reliable, efficient power delivery day in and day out. Take control of your home’s power and shop the 48V ETHOS today, or get in touch with us to get a quote on a custom-built ETHOS system to precisely meet your power needs!
